QuaZIP is a simple C++ wrapper over Gilles Vollant's ZIP/UNZIP package that
can be used to access ZIP archives. It uses Trolltech's Qt toolkit.
QuaZIP allows you to access files inside ZIP archives using QIODevice API,
and that means that you can also use QTextStream, QDataStream or
whatever you would like to use on your zipped files.
QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both reading
from and writing to ZIP archives.
QuaZIP is by default built using Qt4 libraries.
